UNCOUPLING DEVICE FOR CAR-COUPLINGS.

Application filed April 24, 1912, Serial No. 692,837. Renewed November 8, 1915.

To all whom it may concern:

Be it known that I, GARTH GRIFFITHGIm PIN, a citizen of the United States of America, residing at Riverside, in the county of Cook and State of Illinois,- have invented certain new and useful Improvements in Uncoupling Devices for Car-Couplings, of which the following is a specificatlon.

One of the objects of the invention is to provide an uncoupling device comprising at least two elements which are flexibly connected, when the coupling is in anyof its normal positions, by a connection which is so constructed that said elements of the device will automatically separate, in case the coupler is moved outwardly to an abnormal position, due for example: to the failure of the draw-bar, carry-iron, or some other part of the coupling or its, connections; this separate connection preventing such failure of the coupling from tearing the uncoupling device from the car as frequently happens,

under these circumstances, with the type of uncoupling devices heretofore employed.

A further object is to provide an uncoupling device which will be extremely simple in its construction, strong, durable, inexpensive to manufacture, and reliable and effective in its operation.-

In the drawings :-Figure 1 is a front elevation of an uncoupling rigging embodying my invention and attached to a car; Fig. 2 is an end elevation of the same; Fig. 3 is a detail front elevation showing in dotted lines the coupler pin link in different positions to accommodate the. transverse movements ofthe coupler; Fig. 4 is a detail side elevation like Fig. 2, with the operating rod in section, showing in dotted lines, the couple'r'pin link in different positions to accommodate the movements of the coupler under pulling and buffing; Fig. 5 is a view similar to Fig. 4, showing in dotted lines the position of the coupler link in different stages of the coupler under draft, the outermost position indicating that the draw-bar has become loosened from its moorings, the link being shown as dropping from the eye in the operating rod, whereby it is automatically separated from said rod; Fig. 6 is a side elevation of the link.

The reference character 1, designates the end of a car broken away. The coupler 2,

which may be of any approved M. C. B. construction, is connected to thecar in any approved manner. A bracket 3 is secured to the end of the car, near one side thereof, and is provided with an opening 4, constituting a bearing for the operating rod 5.

A center bracket 6, is preferably mounted as shown in the drawings, and is positioned,

when the parts are at rest, substantially in the vertical plane of the coupler or locking pin 11, which pin is provided with an eye at 1ts upper end.

The single link 12, which connects the operating rod with the lock pin is provided at one end with hook 13, at one end to engage the eye of the locking pin and a hook 14, on the other end to engage the eye 10 of the lever of the operating rod, said hook 14, being so shaped that it will automatically be disconnected from the eye 10, of the operating rod lever, upon an abnormal outward movement of the coupler.

From the foregoing description and from the drawings it will be seen that my improved rigging permits the normal draft and buffing and transverse movements of the draw-bar. It will also be seen that in case the draw-bar is moved outwardly to an abnormal position, due for example to the failure of the draw-bar, carry-iron or some other part of the coupling or its connections, the hook 14 will automatically separate from the eye 10- of the lever of the operating rod 5, thereby preventing such failure of the coupling from tearing the uncoupling rigging from the car.

I do not claim herein the features of invention generic to this application and my applications Serial No. 68,211, filed Dec. 22,

1915, and Serial No. 4,431, filed Jan. 26, 1915, which applications are divisions of this application, this application being lim-' ited to the automatic detachment of the link from the operating rod. The features common to thisand the other two applications are claimed in said other applications.

What I claim is 1. An uncoupling device for railway cars, comprising a rod revolubly supported on the end of the car and provided with a crank above the coupler, and a rigid link flexibly connected with the locking pin and connected with the crank by a connection which permits the automatic separation of said crank and link due to an angular movement I of the link relative to the crank upon an abnormal outward movement of the coupler.

.- I g 2. An uncoupling device for railway cars,

comprising a rod revolubly supported on the end of the car, and provided with a crank above the coupler formed with an eye, and a rigid link having a hook on one end engaging the locking pin of the coupler and a hook on the other end engaging the eye of the crank, shaped so that it will be automatically disconnected from the eye upon an abnormal outward movement of the coupler.

3. In an uncoupling device for railway cars, in combination, a coupler, a pin therefor, an uncoupling rod provided with an eye, and a link flexibly attached at its one end to the coupling pin and loosely attached at its other end to the uncoupling rod, the said link being provided at its last mentioned end with a substantially right angled hook, adapted to automatically disengage the link from the uncoupling rod on extreme forward movement of the coupler.

4. In an uncoupling device for railway cars, an uncoupling rod provided with an eye, a coupler, a coupling pin therefor, and

means for connecting the coupling pin and uncoupling rod comprising a single link flexibly attached at one end to the coupling pin, and loosely engaging the uncoupling rod at its other end, the said link being provided at its last mentioned end with a hook adapted to automatically disengage the link from the coupling rod on the extreme forward movement of the coupler.
